Literature Review on Fracture Toughness of different Engineering materials

Authors(2) :-Parth C. Shah, Dr. Naresh Solanki

The present paper gives a technical review of fracture toughness for engineering materials in terms of the linear elastic fracture mechanics. This includes the early investigations and recent advances of fracture toughness test methods and practices developed by various societies. The Basic fracture mechanics parameters for analysis are stress intensity factor K, elastic energy release rate G, crack-tip opening displacement (CTOD) , J-integral and crack-tip opening angle (CTOA) from the basic concept, definition, to, test methods. The important aspect are to guidelines on how to choose an appropriate fracture parameter to characterize fracture toughness for the material of interest, and also how to measure the fracture toughness value defined at a critical point using laboratory specimens. The effects of loading rate, temperature and crack-tip constraint on fracture toughness as well as fracture instability analysis are reviewed.
